Magma Molten rock typically having a temperature between 800° and 1100° C (~1500-2000° F). Magma is the source of high-grade geothermal energy in conventional resources.

Magnetotelluric (MT) Geophysical Method Makes use of naturally occurring electromagnetic waves to image the resistivity structure of the subsurface. The results can reveal the locations of...

Microseismicity Tiny earthquakes that result from slip or shear along a fracture caused by an uneven distribution of stress. The displacements are very small scale and unfelt at the...
